No progress yet, as can be seen on the tracker.

Hi,

I was wondering if any progress was being made with this, I use a SFTP to a cloud storage solution and when I am working on the files I like them to update the cloud copy with each save.

My problem is that the service I use does not allow timestamps to be modified, which means that each save does send the file to the server but also causes WinSCP to display an error.

Hey, any progress on that issue? :cry: It's very important for me. I want to watch local dir with more than one file changes within a minute and to use FTP protocol for uploading.
Is there any estimate when we can expect improvement on "keep remote dir" feature?

Sometimes it may be acceptable and more convenient to have a whole directory uploaded (in case of small-sized directories, e.g. ones with text files) instead of having to wait for a new minute to be able to upload a file.

However, I see a solution for binary transfers. When the timestamp is the same, file sizes could be compared. It solves the problem in most cases.

With a little more effort, sizes could also be compared in text mode (with remote file size being local file size minus number of CRLFs in it).

OK, but that WinSCP will upload whole directory with every change, because the timestamps differ.

Maybe keeping dirs up to date would work better if there was no local-to-remote timestamp comparing for regular FTP servers. Or, at least, if there was an option for turning such comparisons off.

WinSCP gets notification from Windows about change. But only about change in a directory. It does not know a file which has changed. Hence it needs to find yout itself (by comparing timestamps).

Isn't that caused by timezone difference? If you compare times in local and remote panel, do you see the same times?
Ydriuf

I understand.
However, I know a regular FTP server that does not cause that problem even though it lists timestamps with minute precision only.

Here a sample of its raw file list:
150 Opening ASCII mode data connection for file list
drwxr-xr-x 2 xxdyfit-www www 112 Apr 3 10:47 style
-rw-r--r-- 1 bodyfit-www www 4 Jun 16 07:43 test.txt
[...]

And a sample of monitoring log from this server:
10:00:04 Scanning 'Z:\Business\xxdyfit\_site' for subdirectories...
10:00:04 Watching for changes in 46 directories...
(first change)
10:00:06 Change in 'Z:\Business\xxdyfit\_site\trener' detected.
10:00:07 File 'Z:\Business\xxdyfit\_site\trener\test.txt' uploaded.
10:00:08 Change in 'Z:\Business\xxdyfit\_site\trener' detected.
10:00:09 File 'Z:\Business\xxdyfit\_site\trener\test.txt' uploaded.
(second change)
10:00:12 Change in 'Z:\Business\xxdyfit\_site\trener' detected.
10:00:12 File 'Z:\Business\xxdyfit\_site\trener\test.txt' uploaded.
10:00:13 Change in 'Z:\Business\xxdyfit\_site\trener' detected.
10:00:14 File 'Z:\Business\xxdyfit\_site\trener\test.txt' uploaded.
(it looks like here every file is uploaded twice but no idleness issue arises)

Therefore I think the problem might also be in something else than remote timestamp precision.

Another thing is that to effectively monitor local changes WinSCP needs only to remember original local timestamps and to upload files that it knows have changed (when their local timestamps have changed) regardless of whether they have the same timestamp remotely or not.

Usually with FTP, the server reports file timestamp with minute-precision only. Hence WinSCP when comparing time of local and remote time is not able to detect the change, if it happens the same minute as the last one.

Use SFTP is possible.
Ydriuf

I should have also mentioned that I changed the file only once in the second minute but there are two uploads shown in the log.

Keeping dir up to date: frequent changes of the same file

If "Keeping remote directory up to date" for an FTP server is active and a specific file is updated frequently (which happens a lot while e.g. testing remote application), WinSCP fails to update it more often than once in a minute (of local time) on some servers.

It looks this way in the log:

22:23:06 Scanning 'Z:\Business\MBurda.com\_Site' for subdirectories...
22:23:06 Watching for changes in 18 directories...

(first change, file gets uploaded)
22:23:19 Change in 'Z:\Business\MBurda.com\_Site' detected.
22:23:20 File 'Z:\Business\MBurda.com\_Site\index.php' uploaded.
22:23:20 Change in 'Z:\Business\MBurda.com\_Site' detected.

(second change that minute, no action)
22:23:54 Change in 'Z:\Business\MBurda.com\_Site' detected.
22:23:54 Change in 'Z:\Business\MBurda.com\_Site' detected.

(new minute starts, third change occurs and the file gets uploaded again)
22:24:01 Change in 'Z:\Business\MBurda.com\_Site' detected.
22:24:02 File 'Z:\Business\MBurda.com\_Site\index.php' uploaded.
22:24:03 Change in 'Z:\Business\MBurda.com\_Site' detected.
22:24:03 File 'Z:\Business\MBurda.com\_Site\index.php' uploaded.
